ANGEL
Angel was sired by Darla when he was in his early to mid twenties in Galway, Ireland. He spent the next 150 years causing death and destruction wherever he and Darla went. Angelus was finally stopped by the family of a gypsy girl that he killed. Angelus was cursed with the Restoration spell - it returned his soul to his body. Angelus because Angel. Angel wandered around the world, not wanted by Darla and not able to be around humans without guilt.
It
wasn't until Whistler showed Angel the slayer that he decided he wanted to
become something. He came to Sunnydale to help Buffy but ended up falling
in love with her. In order to save her life he even killed Darla.
When two of Angel's fledgling vampires came to Sunnydale the caused havoc
throughout town and in Angel's life. Buffy and Angel stood strong now
matter what was thrown at them and when the two consummated their love the
Restoration spell was broken and Angelus returned. Angelus tried to bring
forth the demon Acathla to swallow the world into hell but Buffy stopped him in
time with the help of Spike. She sent Angel and Acathla back to hell.
After a long time in hell, Angel was released and sent back to Sunnydale.
Buffy helped nurse him back to health and the two couldn't resist the love the
still shared. Angel was haunted by visions of his past and the future he
knew he could never have with Buffy. Angel decided to let Buffy have a
shot at a normal life and he left Sunnydale.
Angel periodically went to Sunnydale when he felt Buffy needed his help - or in the case of the aftermath caused by Faith - to apologize. Angel made things worse by attacking Riley - the new man in Buffy's life. He told Buffy that he didn't like Riley and then left Sunnydale again so that Buffy can lead her own life. Apart from their 'forgotten' day, Angel saw Buffy once more before she died ... he travelled to Sunnydale to comfort her following her mother's funeral, but had to leave when their emotions threatened to get the better of them
